London (CNN)-- Last December, as the first of several worrying Covid-19 variants ripped through the United Kingdom, Prime Minister Boris Johnson made the unwelcome decision to cancel Christmas plans for millions of Brits.

"We are sacrificing our chance to see loved ones this Christmas, so we have a better chance of protecting their lives so we can see them at future Christmases," Johnson said, taking a potentially career-defining step that he had ruled out just days earlier.

Ten months later, the UK's attitude towards the Covid-19 has changed beyond recognition. Virtually all of England's restrictions were lifted in July, with the events and hospitality sectors returning to full capacity as Johnson urged Britons to "begin to learn to live with this virus."

But the Delta variant -- more transmissible still than the Alpha strain which wrecked last year's festivities -- has not gone away.

The country has quietly endured stubbornly high cases, hospitalizations and deaths when compared to the rest of Europe. Britain has registered nearly half a million cases in the past two weeks -- and almost 50,000 on Monday -- more than France, Germany, Italy and Spain combined. The UK reported 223 deaths on Tuesday, the highest daily figure since early March.

Johnson has strayed from much of the European Union in his approach; while a number of countries on the continent have introduced vaccine passports, England halted its original plan to do so. Mask-wearing and social distancing and other measures are no longer required by law in Britain.
